GALVANIC BATTERY'.

'Appnanon and July 1a, i898.

.T all whom lt mifyl concern:

Be it known that I, CHARLES T. RICHMOND,

a citizen of the United States, residing atv Cleveland, in the county ofCuyahoga and 5. State of Ohio, have invented a certain new and usefulImprovement in Galvanic Batteries, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings.

IThe object of my invention is to make a powerful and durable galvanicbattery which will occupy comparatively little space.

The invention consists in the construction and combination of partsconstituting a single cell, and also in the combination of the elementsof two or more Cells with a single containing vessel subdivided intocompartments by a partition or partitions, which serve also to preventcontact between the heads of zo the carbon elements of the individualcells.

In the drawings, Figure l is a side elevation, partly in section, of aduplex galvanic battery containing the invention-that is to say, abattery of two cells in a single Contain- 2 5 ing vessel.

on line2 2 of Fig. l. Fig. 3 is a horizontal .sectional view on the line3 3 of Fig. 1. Fig.

4 is a detached view of the combination of battery elements employed ina single cell. 3o Fig. 5 is a detached View of one of the carbon.cover-plates which constitute the head of -a carbon element. v

Referring to the parts by letters, A represents the head of a carbonelectrode. It is a carbon .plate and of suchshape that lit is adapted torest upon the top of the jar and to serve as a cover therefor, as wellas a sup' 'port for the electrode in the jar, On its under side are twothreaded bosses d a, onto Fig. 2 is a vertical sectional viewY SerialNo. 6861206. (No modeld .means for supporting the electrode and atachingthe circuit-wires thereto-as, for ex- Inple, the threaded stud d', thewasher d2, and the thumb-nut df. Secured to the lower end of this stemare rthe two curved Zinc 5`5 plates [Z4 d5, which lie between the twocarbon cups, the concave side of said plates facing and partlyembracingthe cups. Rubber rings H may surround the carbon cups toprevent contact with the zinc plates. The 6o zincelectrode constructedin the form shown anddescribed presents a large surface for the actionof the battery solution, and it likewise permits a compact assembling ofthe parts which of necessity must be in the jar submerged .in thebattery solution. A binding post J for the carbon element, of any usualform, is embedded in the head A and extends ,upwardly therefroml Thecombination of battery elements, as 7o described, may be placed in anysuitable containing vessel or jar, on the top edges of which the head Amay rest. A jar which approximately is of the form of a rectangle'inhorizontal-section will contain the'elements with 75 comparativelylittle waste room, and for this principal reason is the preferred formfor the containing vessel.

The containing vessel G shown in the drawings is designed to contain twosets of the 8o described elements in the smallest space. It issubstantially square in plan, and it is subdivided by an internalCentral vertical partition g, the top of which extends above the top ofthe sides. The cover-plates or heads A of the carbon electrodes restupon the tops of the sides, and each plate is of such size as to serveas a Cover for the compartment over which it is placed. The upwardextension of the partition g lies between the 9o two cover-plates andprevents contact between them. plete eells in one containing vessel.

Although, as shown, only two compartments are formed in the containingvessel by 'the integral partition, any number of such compartments mightbe similarly formed without departing from theinvention as set forth inthe claims.

There are therefore two eomn Having described my invention, I claimlool. Inha galvanic battery, the Ycombination of a containing vessel withvacarbon plate adapted to serve as acover for said vessel and having twothreaded bosses on its under side,

out through thehoie inthe cover-plate be-4 tween said bosses,substantially as described.

2.In a gaivanic battery, the combinedl cover for the containing vesseland head and support for the carbon element, consisting of a carbonplate having on its under side two threaded bosses, and having abinding-post embedded in it projecting upward from its top surface, andhaving a hole a2 through it between said bosses, combinedwith two 'carbon porous cu ps which are screwed upon said threaded bosses, and a zincelement whose stem passes through said hoie, substantially as specified.

3. In a galvanic battery,the combination of a containing-jar, acarbon'plate adapted to serve as a cover therefor and having twothreaded bosses on-its under side and a hole between said bosses,withtwo carbon porous cups which screw onto said bosses, the'zinc elementconsistin g of two curved plates which lie between said cups with theirconcave sides facing said cupsfand a stem to `which said plates aresecured which passes out through In testimony whereof I hereunto aiiixmy signature in the presence of twov witnesses.
